Within the general area of early main group metal chemistry, the controlled synthesis of well-defined metal hydride complexes is a rapidly developing research field. As group 1 and 2 metal complexes are generally highly ...
The first enantioselective Friedel-Crafts alkylation-acetalization-cascade of naphthols with alpha,beta-unsaturated cyclic ketones and 1H-inden-1-ones was realized. 9-Amino(9-deoxy)epi-quinine A was the catalyst of choic...
The synthesis of a second-generation [6]-helicenoidal DMAP organocatalyst is reported. The synthesis is reliant upon a highly diastereoselective Rh-catalysed [2 + 2 + 2] triyne cycloisomerization, using an existing stere...
Two new dibenzocyclooctyne-thymidine monomers were incorporated into oligonucleotides and crosslinked to azide-labelled complementary strands across the DNA grooves. Equivalent reactions were successful using a (bicyclo[...
Electron-transfer properties of a nonheme Mn(IV)-oxo complex, [(Bn-TPEN)Mn-IV(O)](2+), reveals that Mn(IV)-oxo complex acts as a stronger one-electron oxidant than the Fe(IV)-oxo analogue. As a result, an electron transf...
A combination of complementary cluster ligands results in the formation of a new calixarene-supported ferromagnetic [Mn-5] cage that displays the characteristic bonding modes of each support.
Poly(quinoxaline-2,3-diyl)s bearing pyrene pendants exhibited solvent-dependent changes of the fluorescence color (blue and green) and the screw-sense selectivity (left-handed and racemic) in chloroform and 1,1,1-trichlo...
A new amino substituted tricarboxylate linker and the new metal-organic framework Cu-3(NH(2)btc)(2) have been synthesised. The new MOF shows good adsorption properties and is suitable for postsynthetic modification to fo...
The accurate H-1 positions of alanine tripeptide, A(3), with anti-parallel and parallel beta-sheet structures could be determined by highly resolved H-1 DQMAS solid-state NMR spectra and H-1 chemical shift calculation wi...
Two novel vis-NIR pH probes based on styrylcyanine with acidic pH response are easily synthesized, which display large Stokes shift and high sensitivity. The significant colocalizations of two probes with LysoTracker Gre...
Herein, we report on the folding pattern observed in a synthetic peptide featuring two highly mutually dependent, yet strikingly dissimilar, closed networks of hydrogen-bonded rings that work in a cumulative fashion to s...
Enzymatic transglycosylation has been successfully implemented by beta-galactosidase (beta-Gal) on PEG brushes. Kinetic parameters validate this kind of chemoenzymatic strategy which is promising for construction of biom...
We found that an integrated flow microreactor system enables the preparation of boronic esters bearing electrophilic functional groups using organolithium chemistry and that it allows for their use in Suzuki-Miyaura cros...
We show that DNA containing a conformationally-locked anti analogue of O-6-alkylguanine is a poor substrate for human O-6-methylguanine-DNA methyltransferase (MGMT) and the alkyltransferase-like protein, Atl1. This highl...
A novel solid catalyst featuring a hydrophobic core-hydrophilic shell structure was synthesized for aqueous-phase reactions, which showed significant reaction rate enhancement effects.
The saturated water content in a hydrophobic ionic liquid, 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)-imide, was improved from 0.4 wt% to 17.8 wt% by adding a 3-(1-butyl-3-imidazolio) propanesulfonate-type...
